“…Aritmia merupakan istilah umum untuk setiap irama jantung yang berbeda dari irama sinus normal jantung atau normal sinus rhythm (NSR) [9] [10]. Aritmia yang paling umum dan yang sering dijumpai adalah atrial fibrillation (AF) [11]. Fibrilasi atrium atau AF didefinisikan sebagai irama jantung yang abnormal.…”

ABSTRAKJantung merupakan salah satu organ penting yang terdapat pada tubuh manusia. Fungsi vital yang diperankan oleh organ jantung berpengaruh besar terhadap kondisi seseorang yang dapat dilihat dari isyarat fisiologi yang dihasilkan oleh aktivitas kelistrikan jantung yang dapat diukur dan direkam berupa electrocardiogram (EKG). Tujuan dari penelitian ini adalah untuk mengidentifikasi kelainan jantung atau aritmia berupa atrial fibrillation (AF) pada isyarat EKG. Data penelitian yang digunakan berasal dari Rumah Sakit Umum Daerah Tugurejo Semarang yang terdiri dari data pasien dengan kasus atrial fibrillation (AF) dan data ECG normal atau normal sinus rhythm (NSR). Data yang diambil dalam bentuk data cetak, selanjutnya di lakukan scanning untuk mendapatkan data citra digital agar dapat diproses dengan komputer. Pada penelitian ini terdapat beberapa tahapan, diantaranya adalah pra-pengolahan, ekstraksi ciri, dan klasifikasi. Proses ekstraksi ciri berdasarkan ciri statistik (mean, standard deviation, kurtosis, variance, skewness) isyarat periodogram dari EKG, selanjutnya diklasifikasi menggunakan algoritma Support Vector Machine (SVM) dan Naive bayes Classifier (NBC) sebagai algoritma pembanding. Hasil yang didapatkan pada penelitian ini, SVM memiliki kinerja yang lebih baik dengan nilai akurasi sebesar sebesar 84,0%, sensitivitas 80,5%, dan spesifisitas 92,8%.Kata kunci: fibrilasi atrium, elektrokardiogram, SVM, NBC, periodogram. ABSTRACTThe heart is one of the important organs in the human body. The vital function of the heart organ affects the person's condition which can be seen from the physiological signal resulting from the electrical activity of the heart and can be measured, recorded on an electrocardiogram (ECG) PENDAHULUANPenyakit kardiovaskuler adalah penyakit yang disebabkan gangguan fungsi jantung dan pembuluh darah. Berdasarkan data dari badan kesehatan dunia (WHO) menempatkan abnormalitas jantung sebagai urutan teratas daftar penyebab utama kematian di seluruh dunia [1]. Jantung merupakan suatu organ otot berongga yang terletak di pusat dada. Fungsi utama jantung adalah menyediakan oksigen ke seluruh tubuh dan membersihkan tubuh dari hasil metabolism (karbon dioksida). Jantung melaksanakan fungsi tersebut dengan mengumpulkan darah yang kekurangan oksigen dari seluruh tubuh dan memompanya kedalam paru-paru, dimana darah akan mengambil oksigen dan membuang karbon dioksida, jantung kemudian mengumpulkan darah yang kaya oksigen dari paru-paru dan memompanya ke jaringan di seluruh tubuh [2][3]. Fungsi vital yang diperankan oleh organ yang satu ini berpengaruh besar terhadap kondisi seseorang yang dapat dilihat dari isyarat yang dihasilkan oleh aktivitas kelistrikan jantung. Electrocardiogram merupakan salah satu rekaman isyarat fisiologi utama yang dihasilkan dari aktivitas kelistrikan jantung baik ketika fase repolarisation maupun depolarization [4]. Electrocardiogram (ECG)

“…For example, AF increases the risk of stroke by 5-fold2 and the risk of heart failure by 3-fold 3. AF causes considerable morbidity and mortality, negatively impacts quality of life and well-being and imposes significant burden on health care systems 4. Aging populations, increasing prevalence of comorbidities and more effective treatment of cardiovascular diseases are all contributing to the increasing incidence of AF and its associated health care burden 5.…”

Background:The literature suggests that the prevalence of atrial fibrillation (AF) may be lower in Asian countries than in Western countries. Nevertheless, AF remains a significant public health problem in the region. The burden of AF, the experiences of previous trials and the lack of data on AF and its management in Asia Pacific highlight the need for a comprehensive prospective study of AF management.Methods:The REgistry on Cardiac rhythm disORDers assessing the control of Atrial Fibrillation Asia Pacific (RecordAF-AP) is a prospective, observational survey of the management of recently diagnosed AF patients with 1-year follow-up in 8 countries across Asia Pacific. Eligible patients presenting with AF, treated or not, will be included in the registry and data will be recorded prospectively during follow-up visits at 6 and 12 months.Results:RecordAF-AP will recruit more than 3000 patients. Study recruitment commenced in April 2009 and the final results anticipated at the end of 2011.Conclusions:RecordAF-AP will assess the real-life management of AF patients in Asia Pacific, including a comparison of clinical outcomes in rhythm versus rate control strategies, providing much needed insight into the costs, treatment choices and clinical outcomes of AF patients in this region.

“…A trial fibrillation (AF), despite its prevalence and clinical and financial impact, 1 has remained difficult to treat either pharmacologically or interventionally. 2 Catheter ablation is potentially curative but has demonstrated only modest success in paroxysmal AF and yields relatively poor results when applied to more advanced AF.…”

Background-A key mechanism responsible for atrial fibrillation is multiwavelet re-entry (MWR). We have previously demonstrated improved efficiency of ablation when lesions were placed in regions of high circuit-density. In this study, we undertook a quantitative assessment of the relative effect of ablation on the probability of MWR termination and the inducibility of MWR, as a function of lesion length and circuit-density overlap. Methods and Results-We used a computational model to simulate MWR in tissues with (and without) localized regions of decreased action potential duration and increased intercellular resistance. We measured baseline circuit-density and distribution. We then assessed the effect of various ablation lesion sets on the inducibility and duration of MWR as a function of ablation lesion length and overlap with circuit-density. Higher circuit-density reproducibly localized to regions of shorter wavelength. Ablation lines with high circuit-density overlap showed maximum decreases in duration of MWR at lengths equal to the distance from the tissue boundary to the far side of the high circuit-density region
